From a technical perspective, AFFX is bouncing higher here right around some near-term support at $3.41 with lighter volume. This move is following a recent gap down in price for AFFX that took the stock from around $4.50 to $3.45 with heavy volume. Traders should now look to play the next major breakout trade for AFFX. That trade will hit once AFFX takes out its gap down day high at $3.74, and then its 50-day moving average at $3.93 with high volume.

Traders should now look for long-biased trades in AFFX once it sustains a move or close above those breakout levels with volume that hits near or above 980,937 shares. If that breakout triggers soon, then AFFX could easily rip higher back towards its next major overhead resistance levels at $4.40 to $4.72. Any high-volume move above $4.72 will then put $5.20 to $5.50 into play for AFFX.
